. acheapand durable musicroll which is provided with efficient means forengaging with a coupling by means ofywhich the musicsheet may be rewoundori the roll after play-v It consists of a core having. heads or endsconsisting of an integral flange, sleeve, and projecting portion forminga clutch member adapted to engage with a cooperating clutch member ofthe support or coupling.

In the drawings, Figure 1 represents, partly in elevation, artly invertical section, a music-roll embo ying my invention, to-

gether with a coupling adapted to cooperate therewith. Fig. 2 is avertical section of a portion of a modified roll, together with thecoupling. Fig. 3 is a perspective view of the coupling alone. Fig. 4 isa vertical section of a further modification of the roll, together withthe coupling. Fig. 5 is a perspective view of the end of the music-rollshown. in Fi 4.

Ior clearness of illustration I have omitted in all the figures themusic-sheet, which in practice is secured to and wound upon the core ofthe roll.

1 designates the core, which may be made of paper, aper-board, or otherlight and economica material.

2 designates ahead or end, having a flanged portion 3, adapted to guideand protect the edges of the music-sheet wound on the core, and a sleeve4, extending within the core and secured thereto, in the presentinstance,'by a tubular rivet 5. an annular projecting portion 6, whichin Fig. 1 of the drawings is so formed as to inclose the end of thecore 1. The contour of the annular bead or projection 6 is interruptedor broken by a notch or recess 7, forming o posing walls or shouldersfor enga ing a ci utchin or clutch member.

' he core is a apted to engage and be ro- The head '3 is formed with ashaft 9, which formsa part of the mechanical instrument or player and isin practice provided with means by which it may be ro tated to rewindthe music-sheet on the core 1. The coupling 8 is provided with a centralprojecting portion 10, adapted to fit snugly within the end of thesleeve 4 and with an annular recess 11, adapted to fit over and en cess11 is a tooth or projection 12, adapted to engage in the notch or recess7 in the annulus 6 for rotating the roll.

The modified form of the device shown in Fig. 2 is similar to that shownin Fig. 1 except that the annular projection 61 on the head 2 does notinclose the end of the core 1, and the flange 31 is slightly difiercntin shape from that shown in Fig. 1. It is obvious that the recess 11 inthe coupling 8 is preferably made to fit snugly over the annulus 61, as

before described. g

In the form of the device shown in Figs. 4 and 5 of the drawings thehead 2 is unpro-' clutch engaging projection '62, forming, as in thepreviously-described case, a shoulder adapted to engage with the pinor'projection 12 in the coupling 8 as before. Of course in this form ofthe device there may be a certain amount of lost motion when thecoupling is rotated until the pin 12 engages with the projection 62 torotate the roll.

The head 2 will usually be formed of sheet metal or of some otherdurablev material, while the core 1 may be made, as above described, ofpaper or a relatively cheap article.
